I was working in the field earlier this week and I can't believe I picked up dozens of chiggers. I tucked my pants legs into my socks and then put on knee-high muck boots (was around stream restoration site), sprayed with deet--they still got me. Itching and irritable. I dislike mosquitoe bites, and ticks, both have the potential to transmit nasty diseases, but for pure long-lasting misery, chiggers are the worst.

So, i can't help you. Obviously I went to extreme measures to make sure I wasn't a meal, but to no avail. Make sure you have no standing water around your house is an obvious maintenance requirement. That still doesn't seem to help a lot.

I have an observatory, but really, a simple platform does the job so you're not on the bare ground where ants and spiders roam over your all night. That leaves mosquitos. For those, I wear full clothing and spray down my clothing so its not on me directly and that works well. I supplement that with some Thermalcell MR150 units that seems to do the job.
